Sinkholes have formed in my yard. Who is responsible for filling them?

The County allows this opening to be no more than 7 inches in height. The Department of Public Works and Transportation Office of Highway Maintenance (OHM) can determine if the opening is too large and take any corrective action needed. You may contact the OHM's Customer Service Office at 301-499-8523 to arrange for an inspection of the storm drain.

This is an areaway drain and is the responsibility of the property owner to maintain it. The resident should check to see if the small grate on top of the drain is clogged and clear it if necessary. If the grate is clear, a plumber should be contacted to ensure that the pipe leading from the areaway drain is clear and free of obstructions.
